IMPROVED MACHINE FOR LINTING- AND RELINTING- COTTON-SEEDS AND MOTES The Schedule referredto in these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, GEORGE W. Gnannn, ofMemphis, in the county ot'Shelby, and State of Tennessee, have invented a new and useful Machine for Linting aml Relinting Cotton-Seed and Notes; and I do hereby declare the following to be a snfiiciently full, clear, and exact description of the same, to enable one skilled in the art to which my invention appertains to carry it into eliect, reference being had to the accompanying drawings, which are made part of this specification.

The objects of my invention arc First, to effect the coiiipletc removal of the lint or fibre and the cleaning of the seed and motes in a single compact machine;

Second, to separate the difi'erent qualities or grades of lint or fibre; and

Third, to adaptthe wear of the machine to be readily compensated for and its action regulated.

'lwo ginningcylimlers and their accessories are arranged in a suitable casing, in such relative position and so operated as that the seed and motes, aft-er the long lintor fibre has been removed by the first, passing to the other, shall have the removal of the lint or fibre entirely completed; the breast or concave of the second or last cylinder being constructed with a raspsurface and peculiarly vibrated, for the purpose of insuring the perfect cleansing of the seed and motes by rolling them on saidcylinder,.aml thus bringing all their surfaces in contact therewith, and suitable shields or guides employed to retain the seed and motes atthe centre of said cylinder and prevent their escape at the ends of the vibrating breast thereof.

The casing is provided on opposite sides, with two diseharge-apertures for the lint or fibre, so arranged as that the lint or fibre removed by each cylinder is discharged separately through them.

The strips or brushes of the brush-cvlimlcrs are held by transverse bolts passing through radial slots in the heads of said cylimlcrs, and are thus adapted to be adjusted to compensate for wear, or to regulate their action on the giiming-eylimlers as required, and the rollers employed to throw back the seed from the ginning-cylimlers made adjustable relatively thereto for said purposcs.

In the drawings Figure 1 represents a front elevation of a machine illustrating my invention;

Figures 2 and 3. elevations of the respective cnds thereof;

Figure 4, a plan view;

Figure 5, a vertical transverse section;

Figure 6, a vertical longitudii'ial section of one cud; and

Figures 7 and 8 respectively, a time view and trans-.

verse sectiomon an enlarged scale, of the vibrating breast or concave of the second cylinder, detached.

Similar letters of reference indicate like parts ll! the several figures.

A represents the casing, which may be constructed of the usual or any suitable material, in suitable manner, and of any suitable form to adapt it for the reception of the opcrative parts of the machine, and to receive and discharge the lint or fibre and seed and motes, as herein described;

B 13 represent the ginning-cylinders;

G C', the rollers for throwing backthe seed and motes;

l) I), the luush-cylinders; and

E E, the breasts of the two ginning-cylinders.

The cylinders BB and rollers Q'G' may be of any usual or other suitable form, but are preferably construct-ed respectively (the cylinders) with wire teeth, secured in place by means of soft I metal cast around them, as described in the expired patent of John L.

Tnttle, granted October 30, 1849, or in other suitable 1 manner, and (the rollers) with lmigitudinal spiral grooves, as in the form in common use.

The ln'ush-cylinders D D are'preferabiy constructed with cast heads, provided with suitable radial shoulders on their peripheries, for the support of the brushes or strips which are held up to them by. means of transverse bolts 11 (figs. '5 and 6) passing through radially-elongated slots in lugs (1', on the inner sides of the heads, this construction adapting said cylinder to be expanded to compensate for wear, and to regulate the action of the brushes on the ginningcylinders. The rollers G G are also preferably made adj ustablc relatively to the ginning-cylimlers, by being mounted in sliding boxes 1" F, adj ust-able by means of screws ff passing through their down-turned ends and hearing against the supports of the boxes, as shown, or in other suitable manner, to regulate their act-ion! as requircd.

The breast E is constructed of the usual or any suit-able form to adapt it to receive the seed-cotton and feed it to the ginning-cylinder B.

The breast'E is preferably constructed with a raspface, as represented in: figs. 7 and S, and vibrated vertically and horizontally, being guided in its vertical movement concentrically with the cylinder B, as hereinafter more particularly describcd.

The two sets of scparating-devices B, C, D, E, and B, O, 1), E, being arranged relatively to each other, aml operating substantially as indicated in fig. 5, the seed and motes, as separated by the former, pass, by a snitably-arranged passage, l, to the latter, where the removal of the lint or fibre therefrom is completed, and said seed and motes discharged through a passage, II, into a suitable receptacle, the dirt and dust scparalwl by the lirst setfalling through an opening, I, and the lint or libre removed by each being separately discharged through apertures J J, the currents of air produced by the brush-cylinders serving for the latter purpose, as in the 'connnon gins.

8 represents a set-screw or adj nstable stop, attached to the breast l), at a suitable point below its hinge, and abutting against the edge of one oftbc ends of the casing, employed to regulate the distance of said breast from the cylinder B, and the consequent area ofthe passage G, and rapidity of the discharge of the seed and motes therethrough, as required.

G represents ashield or guide applied in the space below the passage G, between the cylinders B and B, to conlinc the seed and motes to the-front and centre of the cylinder B, and thus prevent its escape at the ends ofthe breast E, and behind said cylinder B, and secure the. perfect treatment of it all.

K represents a horizontal shaft, which is mounted in vertically-sliding boxes, and allowed an axial or longitudinal motion therein,- for a purpose which will presently appear.

The breast E is hinged to theshaft K by means of lugs L L, and connected therewith, so as to receive a horizontal longitudinal movement through it by means of collars M M attached to said shaft, between the lugs L L, the object of said shatt being to guide said breast in saiddongitudimtl movement, and to support it in front, and at the same time to permita vertical curvilinear movement thereto, hereinafter described.

N represents a rod or pitman, connecting the breast E to the wrist of a crank-disk O, on the .end of a rotary shaft, 1, at right angles to said shattK, to impart to it the described longitudinal reciprocation, being preferably connected thereto by means of one of the collars M, shaft K, and lugs L, as shown.

Q Q represent vertical links, connecting the lower edge ofthe breast l with the frame of the machine, being preferably attached to the former through one of the collars M, the shaft K, and lugs L, as shown.

It represents a proje tion at the lower edge of said breast, having a cm'ved slot in the form of an arc, with a sine parallel with the shaft K, aml ot' a length equal to its (the breast E"s) longitudinal movement; and

S, a stationary stud ,or friction-roller, occupying the slot in the projectionlt, and traversing it in said longitudinal movement of the breast.

The effect of these provisions is to produce from the horizontal longitudinal movement, imparted definitely to said breast, in addition to said movement, a vertical movement in acurved path, which is made concentric with the cylinder B, or nearly so, by a proper adj ust .ment of the curve of the slot in the projection R, relatively to the extent of the vertical movement, said extent being determined by the. links Q and the extent of horizontal movement, whicltlatter is determined by the stroke of the crank-disk O.

A table 'or shelf, '1, attached to the .ends of the casing A, and extending across its front, may atford a base for brackets or standards 1 t' t", for the reception or support, respectively, of the sliding boxes of the shatt-K, the links Q, and the stud S.

An arm or bracket, U, attached to one end of the casing, and provided with a suitable box at its upper extremity, may t'orm the support of the shaft P.

The rasp-face of the breast E, as shown most clearly in figs. 7 and S, is composed of zigzag teeth or projections, c, having square upper surfaces and bevelled lower surfaces, andinclined alternately toward opposite ends of the breast, as represented.

That portion only of the breast E, provided with the rasp-surface, may be made of metal, the remainder being made ofwood, and suitably attached thereto, as

shown, or the whole may be made of metal in suitable I manner.

The provision of the breast E with the rasp-t'ace, as described, causesitto hold the seed and motes in contact with the final glnning-cylimler, and roll them over its surface.

The latter result further seemed by the vibration of said breast, as described, the seed being thereby rolled back and forth over the surface of the cylinder, and all their various surfaces brought in'contact therewith, thereby sccuring the removal ofevery portion of the lint or fibre, without liability of the seed being crushed or becoming jammed between the cylinder and breast.

\1 represents the driving-pulley, which, as shown, is on one end of the shaft of the cylinder B.

\V W represent spur-gears on the'shafts of the cylinders B B respectively, and on the same end of the machine as the. driving-pulley V, for connecting said cylinders.

X X Y Yrepresent pinions on the shafts of the rollers C malt", and the shatts of the brush-cylinders D and 1) respectively, am] on the opposite'end of the machine to the wheels \V \V; and

Z Z represent donble'or internally and externallygeared spur-wheels on the shafts of the cylinders it and B respectively, imparting their movementto said piuion's X Y and X Y respectively, X and X meshing with their internal gear, and Y and Y with their external gear, as .shown.

The rollers'U (f and brush-cylimlersI) D thus re celve movement at a proper relative rate of speed.

P represents a bevel-pinion, on the same end of the shatt 'ot' the cylinder B as the spur-wheel Z, (external thereto,) and I a corresponding bevel-gear on the" shaft I of the Clank-disk O, by which the breast- 16 is vibrated, and which thus receives its motion.

The adjustable boxes of the rollers C G, sliding horizontally, as shown, or concentrically, ornearly so, with the spur-wheel Z Z, adapt their adjustment to be made without injurionslyatfeeting the mesh of the pinions \V \V'.-

The, gearing may all obviously be arranged on one end of the machine, if preferred, or a suitable arrangement of belts aml pulleys substituted therefor.

The precise construction, combination, and arrangement of parts shown and described may also'obviously be varied as reqnirtal for ditt'erent purposes.

Having thus described my invention,

The ibllowing is what I claim as new therein, and desire to secure by Letters Patent:

1. The combination and arrangement of two ginningcylinders B B and their accessories, the first for re-. moving the long lint or fibre, and the second to complete the cleaning of the seed and motes, substantially ashcrein described.
